Specification of Letters Patent.

Application led September 2, 1919. Serial No. 321,258.

To all whom t may concern:

Be it known that I, JOSEPH ANNICQ, a subject of the Belgian King, and resident of Renaix, Belgium, have invented certain new and useful Improvements in Processes of Dyeing, Washing, and Similarly Treating Yarns in the Form of Hanks, Skeins, o r the like, of which the following is a specification.

The present invention relates to improvements in the process and machines for dyeing, washing, hydroextracting or similarly treating yarns, and more especially cotton yarns, inthe form of hanks, skeins, bundles and the like. y

The novel process consists substantially in making up the yarn in its natural, dry state, in shape of hanks or skeins, into large bundles of about two hundred pounds, in such a way as to have all the threads running approximately in the same direction, which also the direction of fiow of the dyeing or the like liquid, in pressing said bundles in a hydraulic or the like press into cylindrical bundles of about twenty eight inches in diameter, whereby the most of the air is expelled from the yarn and encircling the thus compressed bundles or packs by means of iron hoops formed in two portions connected together by means of a removable key, as will be clearly explained hereinafter.

Of course the pressure to be applied depends on the class of yarn, for instance a two pound bundle of soft single yarn having a full length of twenty five inches should be compressed until its cross section is reduced to somewhat less than one square inch; hard spun sewing yarn to about three quarters of a square inch.

The material thus'compressed in shape of a cylindrical bundle or pack is introduced into a tank of about thirty inches inner diameter having a perforated bottom partially covered with a wire gauze diskv and a removable cover provided with a central opening into which is engaged a resilient tube for supplying the dyeing or the like liquid. Said tank is located in an open dyeing vat.

The bundle or pack surrounded by hoops being introduced into the tank with the threads vertically directed, the key connecting the various hoops made in two parts, is removed, whereby the hoops are released and the material expands and fills the whole tank. Then the cover is put on top of the tank and the liquid introduced through the resilient tube by means of a force pump. The liquid forced downward through the yarn follows the direction of the threads. The disk of wire gauze does not cover the whole perforated bottom of the tank; an annular space remains uncovered, this uncovered bottom space forming with the compressed yarn an annular joint preventing the liquid from directly escaping through said annular bottom portion. Thus Ythe liquid, carrying with it the air between the threads, is forced through the central portion of the perforated bottom and enters the surrounding dyeing vat. After the liquid has reached the required level in the vat, the cock of a connecting tube between the vat and the pump is opened, so that the material remains under the action of the flowing liquid during the time required for the dyeing, washing or the like purposes. .y

Then the cylindrical tank is removed from the vat and placed upon an exhausting device operated by means of a vacuum pump which expels the remaining liquid from th material.

Finally the latter may be treated by hot air or steam by means of a pump, for drying or oxidizing purposes. Then the cover is removed and the tank is emptied of its contents which are forwarded to the drying room.

. The accompanying drawings, givenby way of example, illustrate the various devices of which I make use in the above process. I n said drawings Figure 1 is a view of what is commonl known in the trade asa one pound roll or bundle of hanks as delivered from the spinners. v

Fig. 5 is a lateral view corresponding to Fi 3 of the press without materlal.

Fig. 6 is a view of a packed bundle ready for being inserted into the dyeing tank.

Fig. 7 is an axial section through the tank.

Fig. 8 is an axial section through the whole of the dyeing machine.

Fig. 9 is a sectional view of a portion of an exhauster arranged for being connected with the bottom of the dyeing tank and with an exhaust pump.

0n the arc shaped pressure plate 2 (Fig. 3) of the press, a number, say two hundred of such one pound rolls are arranged alongside and above each other, in parallel relation, a key 9 and two or four iron strips 5 made in two portions connected by key 9 being previously laid on the plate 2, for the purpose explained hereinafter, as clearly shown in Figs. 3 and 4.

The press head proper comprises two angle irons 3 or guides along which slides the pressure plate 2 and secured at their ends on the base frame ofthe press (not shown), said irons being bent at their middle portion in semicircular shape. A plurality of T shaped irons 4 are interposed between the angle irons 3 and in parallel relation with each other and with the latter, thus forming a frame within which is arranged and maintained the material to be pressed. The T irons 4 are maintained by stay bolts 6 (Figs. 3 and 5).

The pressure plate 2 being raised in the position shown on the left in Fig. 3, by hydraulic or the like pressure, the metal strips 5, provided with eyes 7 and buttons 8, are

turned down around the circular bundle of material thus encircling the latter, and they (tre. hel d in position by a key plate 9.

The cylinder shaped compressed bundle is now removed from the press and is introduced into the dyeing tank 10 (Fig. 7 located within a vat or reservoir 13 for the dye or other liquid (Fig. 8) having solid sides and an open top.

The dyeing tank 10, is cylindrical and has an inner diameter of about thirty inches; it is provided with a perforated bottom on the middle part of which is placed a closely woven wire gauze, the outer annular space of the bottom being in direct contact with the material to be treated.

It is provided with a cover 12 having a' central opening into which is fitted an elbow 14 through which theY `d eing or the like liquids enter the tank. e elbow 14 may be connected bymeans of a joint witha tube 15 through which a rotary force pump (not shown in the drawing) forces the dyeing or the like liquid into the tank 10 under a pressure of about one and one-half atmosphere.

The circular bundle haring been introf 11, while on'the annular portion of the perforated bottom not covered by the wire gauze the yarn forms an automatic joint preventing the liquids from\ escaping. The dyeing or the like liquid runs into the vat 13. When the latter is filled up .to a desired level, as for instance at 17, a discharging tube 16 is put in connection with the suction part of the pump, whereby the liquid is maintained in motion during the required space of time, say 20 minutes in the dyeing process, five minutes in the washing process.

When the material has been treated in the tank 10, the latter is removed from the vat 13 and placed upon an exhausting plate 18 lfitting the bottom of the tank (Fig. 9) and the latter connected with a vacuum pump (not shown) which draws away the remaining liquid from the material.

Eventually the tube or elbow 14 may be connected to a source of steam or hot air, sol

that a current of steam or hot air may flow through the material for drying, hydroextracting and oxidizing purposes respectivel Aer every drop of liquid has been-expelled, the cover 12 is removed and the material withdrawn, arranged on a convenient f table or floor and forwarded to the drying room.

Instead of making use of the press illustrated on the drawings and described by way of example, for compressing the bundle of textile material, any other convenient pressing device may be used.

It is understood that the present invention is not limited to the constructive forms described and illustrated by way of example; any other constructive forms of the details may be applied without departing from the principle of the invention.

Having now fully described my said invention, what I claim and desire to secure by Letters Patent, is:

1. The process'of dyeing yarn consistinging a washing solution through the chamber* and the yarn, removing the excess liquid by applying a vacuum to one end of the chamber and then removing the yarn from the chamber for dryin 2. The process 0% dyeing yarn, consisting of, compressing a quantity of yarn having the threads running substantially in one direction, and placing the yarn in a chamber, subsequently releasing the pressure allowing the yarn to evenly expand to fill the chamber, maintaining a uniform pressure on all the yarn, dyeing the lyarn by forcing a dye solution through the chamber in the same direction as the threads, washing the yarn of the excess dye solution by forcing a washing solution through the chamber and the yarn, removing the excess liquid by applying a vacuum to one end of the chamber and then removing the yarn from the chamber for drying.

3. The process of dyeing yarn, consisting of compressing a quantity of yarn having the threads running substantially in one direction, and placing the yarn in a vertically disposed chamber, subsequently releasing the pressure to allow the yarn to evenly expand filling the chamber, so that a uniform pressure is exerted on all the yarn, the threads of the yarn being in a vertical position, dyeing the yarn, by forcing a dye solution into the top portion of the chamber so that it will run down through the yarn along the threads, washing the yarn of the excess dye solution, by forcing a washing solution into the top portion of the chamber so that it will run downward throu h the yarn, removing the excess liquid I) applying a vacuum at the lower end o the chamber and then removing the yarn from the chamber for drying purposes.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
